Small Modular Reactors; Zoning Approval

This bill prevents counties from restricting the construction and operation of small modular reactors if certain federal safety approvals are in place.

What This Bill Does

  • It says county zoning laws cannot prevent or limit the construction and operation of a small modular reactor (SMR) if it meets specific federal safety requirements before starting construction.
  • The SMR must have an early site permit from a federal agency that oversees nuclear safety.
  • The SMR must also get design certification from a federal agency for its safety design.
  • Before building, the owner or operator of the SMR needs to show proof of these approvals to the county board of supervisors.

Who It Names or Affects

  • Counties in Arizona that have zoning laws
  • Companies planning to build small modular reactors

Terms To Know

Small Modular Reactor (SMR)
A smaller version of a nuclear reactor that can be built in sections and is easier to manage than larger traditional reactors.
Early Site Permit
A federal approval given before construction starts, ensuring the site meets safety standards for building a nuclear facility.

Limits and Unknowns

  • The bill does not specify what happens if counties do not follow these rules.
  • It is unclear how this will affect existing county zoning laws that already allow SMRs.

Legislature, Second Regular Session

FACT SHEET FOR
H.B. 2795

small modular reactors;
zoning; approval

Purpose

Prohibits county
ordinances from restricting the use of land for the construction of a small
modular reactor (SMR) if, prior to the construction, the SMR provides evidence
of adherence to outlined federal site permits and design certifications to the
corresponding county board of supervisors (county BOS).

Background

In 1969, the
Legislature adopted the Western Interstate Nuclear Compact (Compact). The
Compact states that party states of the Compact recognize that the proper
employment of scientific and technological discoveries and advances in nuclear
and related fields and direct and collateral application and adaptation of
process and techniques, properly correlated with the other resources of the
region, can assist substantially in the industrial progress of the west and the
further development of the economy of the region. The Compact also states that
it is the policy of the party states to undertake such cooperation on a
continuing basis and that it is the purpose of the Compact to provide the
instruments and framework for such a cooperative effort in nuclear and related
fields, to enhance the economy of the west and contribute to the individual and
community

well-being of the region's people (
A.R.S.
� 30-701
).

The county BOS
may adopt a zoning ordinance to conserve and promote the public health, safety,
convenience and general welfare. The zoning ordinance and all rezonings and
zoning regulations amendments adopted must be consistent with and conform to
the adopted comprehensive plan (‎
A.R.S.
� 11-811
).

There is no anticipated fiscal impact to the state General Fund
associated with this legislation.

this section, mining does not include aggregate mining operations in an
aggregate mining operations zoning district established pursuant to this
section. The board of supervisors of any county with a population of
more than two million persons shall designate and establish the boundaries of
an aggregate mining operations zoning district on the petition of at least one
hundred persons who reside within one-half mile of an existing aggregate
mining operation.� In addition, the board of supervisors of any county may
establish, in its discretion and on the board's initiative, one or more
aggregate mining operations zoning districts. Aggregate mining
operations zoning districts may only be located in areas that are inventoried
and mapped as areas of known reserves or in areas with existing aggregate
mining operations.� Subject to subsections E and F of this section, a county
and the state mine inspector may jointly adopt, as internal administrative
regulations, reasonable aggregate mining operations zoning district standards
limited to permitted uses, procedures for approval of property development
plans and site development standards for dust control, height regulations,
setbacks, days and hours of operation, off-street parking, screening, noise,
vibration and air pollution control, signs, roadway access lanes, arterial
highway protection and property reclamation for which aggregate mining
operations are not otherwise subject to federal, state or local regulation or a
governmental contractual obligation. Regulations
that
are
jointly adopted pursuant to this subsection by the county and the
state mine inspector shall not prohibit the activities included in the
definition of mine pursuant to section 27-301, paragraph 8 or duplicate,
conflict with or be more stringent than applicable federal, state or local
laws.

D. The board of supervisors of any county that
establishes an aggregate mining operations zoning district shall appoint an
aggregate mining operations recommendation committee for the
district. The committee consists of not more than seven operators,
or representatives of operators, of active aggregate mining operations in any
district within the county and an equal number of private citizens, who are not
operators, who are not employed by operators and who do not represent operators,
residing within three miles of the boundaries of aggregate mining operations or
a proposed aggregate mining operation in the district for which the committee
is established.� The initial members appointed to the committee shall be deemed
the primary members, and the board of supervisors shall appoint not more than
five alternate members who represent operators and shall appoint not more than
five alternate members who are private citizens.� Alternate members may serve
at meetings of the committee when a primary member is unable to
attend. An aggregate mining operator may serve on more than one
committee in the same county.� The board of supervisors shall determine the
length of terms of members of the committee and shall stagger the initial
appointments so that not all members' terms expire at the same time.� Members
of the committee who no longer qualify for membership as provided by this
subsection are subject to removal and replacement by the board of supervisors.�
The committee shall elect a member who is an aggregate mining operator to serve
as chairperson for the first year in which the committee is
created. For each year thereafter, the chairperson shall be elected
by the members of the committee with a member who is a private citizen and a
member who is an aggregate mining operator serving as chairperson in alternate
years.� The committee is subject to the open meeting requirements of title 38,
chapter 3, article 3.1.

E. Within ninety days after an aggregate mining
operations recommendation committee is established, the committee shall notify
all existing aggregate mining operators in the district of the application of
this section and title 27, chapter 3, article 6 to the aggregate mining
operation.� In addition, the committee shall:

1. By a majority vote
of all members make recommendations to the board of supervisors for aggregate
mining zoning districts and administrative regulations as provided in this
section. The board of supervisors may adopt or reject the
recommendations but may not make any modifications to the recommendations
unless the modification is approved by a majority of the members of the
recommendation committee.

2. Serve as a forum for mediation of disputes
between members of the public and aggregate mining owners or operators.� If the
committee is unable to resolve a dispute, the committee shall transmit the
matter to the state mine inspector, with written findings and recommendations,
for further action.

3. Hear written complaints filed with the state mine
inspector regarding alleged material deviations from approved community notices
for aggregate mining operations and make written recommendations to the state
mine inspector pursuant to section 27-446.

F. Any administrative regulations adopted by a board
of supervisors pursuant to this section are not effective until the regulations
are approved by the state mine inspector.� The
state mine
inspector
may disapprove the administrative regulations adopted by the board of
supervisors only if they duplicate, conflict with or are more stringent than
applicable federal, state or local laws, rules or regulations. If
the
state mine
inspector disapproves the administrative
regulations, the
state mine
inspector must provide
written reasons for the disapproval. The
state mine
inspector
shall not make any modification to the administrative regulations as adopted by
the board of supervisors unless the modification is approved by a majority of
the members of the board of supervisors.

G. A person or entity is subject to this chapter if
the use or occupation of land or improvements by the person or entity consists
of or includes changing, remanufacturing or treating human sewage or sludge for
distribution or resale.� These activities are not exempt from this chapter
under subsection A, paragraph 2 of this section.

H. A county shall not require as a condition for a
permit or for any approval, or otherwise cause, an owner or possessor of
property to waive the right to continue an existing nonconforming outdoor
advertising use or structure without acquiring the use or structure by purchase
or condemnation and paying just compensation unless the county, at its option,
allows the use or structure to be relocated to a comparable site in the county
with the same or a similar zoning classification, or to another site in the
county acceptable to both the county and the owner of the use or structure, and
the use or structure is relocated to the other site.� The county shall pay for
relocating the outdoor advertising use or structure
,

including the cost of removing and constructing the new use or structure that
is at least the same size and height. This subsection does not apply
to county rezoning of property at the request of the property owner to a more
intensive zoning district.

prescribed in section 27-441.

3. "Aggregate mining operation" means
property that is owned, operated or managed by the same person for aggregate
mining.

4. "Operators" means persons who are
actively engaged in aggregate mining operations within the zoning district or
proposed zoning district and who have given notice to the state mine inspector
pursuant to section 27-303.
